Comparison of models assessing linear and non-linear age associations with children’s cooperation, and whether this association varies by camp, using a linear multi-level model (n = 179, camps = 14).

Comparison of models assessing linear and non-linear age associations with children’s cooperation, and whether this association varies by camp, using a linear multi-level model (n = 179, camps = 14).本研究采用线性多层模型（linear multi-level model），对比了用于同时评估儿童合作行为与年龄的线性及非线性关联、以及该关联是否因营地不同而存在差异的各类模型，本次分析的样本量为179，共涉及14个营地。
